Definitions

  • the present invention relates to ethynyl derivatives of formula I wherein
  • NAM metabotropic glutamate receptor antagonists
  • Compounds with a similar main core have been generically described as positive allosteric modulators of the mGluR5 receptor.
  • highly potent mGluR5 antagonists were obtained instead of mGluR5 positive allosteric modulators, which have a completely opposite pharmacology if compared with positive allosteric modulators.
  • a mGluR5 positive allosteric modulator leads to increased receptor activity (Ca 2+ mobilization) in presence of a fixed concentration of glutamate, whereas an allosteric antagonist (negative allosteric modulator, NAM) leads to a reduction of receptor activation.
  • Compounds of formula I are distinguished by having valuable therapeutic properties. They can be used in the treatment of anxiety and pain, depression, Fragile-X syndrom, autism spectrum disorders, Parkinson's disease, and gastroesophageal reflux disease (GERD).
  • the transmission of stimuli takes place by the interaction of a neurotransmitter, which is sent out by a neuron, with a neuro-receptor.
  • Glutamate is the major excitatory neurotransmitter in the brain and plays a unique role in a variety of central nervous system (CNS) functions.
  • the glutamate-dependent stimulus receptors are divided into two main groups.
  • the first main group namely the ionotropic receptors, forms ligand-controlled ion channels.
  • the metabotropic glutamate receptors (mGluR) belong to the second main group and, furthermore, belong to the family of G-protein coupled receptors.
  • these eight receptors can be sub-divided into three sub-groups: mGluR1 and mGluR5 belong to group I, mGluR2 and mGluR3 belong to group II and mGluR4, mGluR6, mGluR7 and mGluR8 belong to group III.
  • Negative allosteric modulators of metabotropic glutamate receptors belonging to the first group, can be used for the treatment or prevention of acute and/or chronic neurological disorders such as Parkinson's disease, Fragile-X syndrome, autistic disorders, cognitive disorders and memory deficits, as well as chronic and acute pain and gastro-esophageal reflux disease (GERD).
  • acute and/or chronic neurological disorders such as Parkinson's disease, Fragile-X syndrome, autistic disorders, cognitive disorders and memory deficits, as well as chronic and acute pain and gastro-esophageal reflux disease (GERD).
  • GSD gastro-esophageal reflux disease
  • treatable indications in this connection are restricted brain function caused by bypass operations or transplants, poor blood supply to the brain, spinal cord injuries, head injuries, hypoxia caused by pregnancy, cardiac arrest and hypoglycaemia.
  • Further treatable indications are ischemia, Huntington's chorea, amyotrophic lateral sclerosis (ALS), dementia caused by AIDS, eye injuries, retinopathy, idiopathic parkinsonism or parkinsonism caused by medicaments as well as conditions which lead to glutamate-deficiency functions, such as e.g. muscle spasms, convulsions, migraine, urinary incontinence, nicotine addiction, opiate addiction, anxiety, vomiting, dyskinesia and depressions.
  • ALS amyotrophic lateral sclerosis
  • mGluR5 disorders mediated full or in part by mGluR5 are for example acute, traumatic and chronic degenerative processes of the nervous system, such as Alzheimer's disease, senile dementia, Parkinson's disease, Huntington's chorea, amyotrophic lateral sclerosis and multiple sclerosis, psychiatric diseases such as schizophrenia and anxiety, depression, pain and drug dependency ( Expert Opin. Ther. Patents (2002), 12, (12 )).
  • WO02/062323 discloses the use of mGlu5 receptor antagonists for the treatment of pruritic conditions. Alagille et al. (Bioorg. Med. Chem. Lett.
  • WO2014/060384 discloses ethynyl derivatives which are mGluR5 antagonsits useful for the treatment of anxiety, pain, depression, Fragile-X syndrome, autism spectrum disorders, Parkinson's disease and gastroesophageal reflux disease.
  • Selective mGluR5 antagonists are especially useful for the treatment of disorders where reduction of mGluR5 receptor activation is desired, such as anxiety and pain, depression, Fragile-X syndrome, autism spectrum disorders, Parkinson's disease, and gastro esophageal reflux disease (GERD)
  • Objects of the present invention are compounds of formula I and their pharmaceutically acceptable salts, the above-mentioned compounds as pharmaceutically active substances and their production.

  • NAM mGluR5 receptor
  • FIG. 1 The main difference between positive- and negative allosteric modulators can be seen in figure 1 .
  • An mGluR5 positive allosteric modulator (PAM) leads to increased receptor activity (Ca 2+ mobilisation) in presence of a fixed concentration of glutamate whereas an allosteric antagonist (negative allosteric modulator, NAM) leads to a reduction of receptor activation.
  • a monoclonal HEK-293 cell line stably transfected with a cDNA encoding for the human mGlu5a receptor was generated; for the work with mGlu5 Positive Allosteric Modulators (PAMs), a cell line with low receptor expression levels and low constitutive receptor activity was selected to allow the differentiation of agonistic versus PAM activity.

  • the agonist L-glutamate was added to the cells at a concentration corresponding to EC 20 (typically around 80 ⁇ M) with on-line recording of fluorescence; in order to account for day-to-day variations in the responsiveness of cells, the EC 20 of glutamate was determined immediately ahead of each experiment by recording of a full dose-response curve of glutamate.
  • cDNA encoding human mGlu 5a receptor was transiently transfected into EBNA cells using a procedure described by Schlaeger and Christensen [Cytotechnology 15:1-13 (1998 )].
  • Cell membrane homogenates were stored at -80°C until the day of assay where upon they were thawed and resuspended and polytronised in 15 mM Tris-HCl, 120 mM NaCl, 100 mM KCl, 25 mM CaCl 2 , 25 mM MgCl 2 binding buffer at pH 7.4 to a final assay concentration of 20 ⁇ g protein/ well.
  • membranes were filtered onto unifilter (96-well white microplate with bonded GF/C filter preincubated 1 h in 0.1% PEI in wash buffer, Packard BioScience, Meriden, CT) with a Filtermate 96 harvester (Packard BioScience) and washed 3 times with cold 50 mM Tris-HCl, pH 7.4 buffer. Nonspecific binding was measured in the presence of 10 ⁇ M MPEP. The radioactivity on the filter was counted (3 min) on a Packard Top-count microplate scintillation counter with quenching correction after addition of 45 ⁇ l of microscint 40 (Canberra Packard S.A., Zurich, Switzerland) and shaking for 20 min.
